I don't know any such program but I suppose they exist. The problem is probably generaly unnoticed by the people running the program. FWIW OpenBSD 2.6 has the same problem but Linux (kernel 2.0 and 2.4) is unaffected. Did you look at the patch by Bruce at http://groups.yahoo.com/group/freebsd-current/message/39605 ? Bruce, is it still fresh in your memory? Can you comment on the patch - can it be commited in some form? -- Michal Mertl mime@traveller.cz To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
